This is the capability to interrupt the frequency of sounds transmitted through the materials.
N.B.: Noise reduction capability is heavily dependant on the type of concrete slab onto which the raised flooring will be installed.
The capability of calcium sulphate is good thanks to its compact and uniform structure. Despite the fact that the density of wood conglomerate is half that of calcium sulphate, it has a slightly better reduction capability, due to its physical composition. Lastly, X-floor is between the two.
It should be noted that the possibility of raised floor resonance effects is strictly related to the morphology and architectural peculiarities of the building itself.
